Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

If the ACA places more of the burden of health care on the poor and the middle class, diverts resources into waste and unnecessary treatments, coddles an industry culture of dangerous sloppiness, and crowds out all other social priorities, then it will have actively hurt the very people it was intended to help.

Goldhill is the CEO of the Game Show Network, a member of the board of the Leapfrog Group, and will speak at a Cato forum on his book tomorrow, Wednesday, September 18, from 12-1:30 p.m. at the Cato Institute. The Brookings Institution’s Kavita Patel and I will provide comments.

How big can a company get with just 50 employees? We’re about to find out.

Thousands of small businesses across the U.S. are desperately looking for a way to escape their own fiscal cliff. That’s because ObamaCare is forcing them to cover their employees’ health care or pay a fine—either of which will cut into profits and stymie future investment and growth…

“Going protean” offers a better strategy for many businesses. Owners of protean companies create a core of strategic employees who manage the big-picture elements of the enterprise—the culture, business model, product mix, vision, strategy, etc. This core then outsources the business tasks to other corporations…

Non-core tasks could include things like accounting, marketing, product development, manufacturing, IT, PR, legal, finance, etc. There is almost nothing that cannot be outsourced…

These new contracts will be a mix of large corporations, small businesses, micro-corporations and even nano-corporations (an individual doing business as a corporation). But to be a protean solution, it must involve a corporation-to-corporation relationship…

In the context of ObamaCare, a small business could go protean by offering current employees contracts for doing their current work as a corporate entity instead of as an employee…

[A]s government continues to impose itself into the marketplace and reduce the freedom of the commercial sector through statist programs like ObamaCare, businesses will have to look for creative solutions to survive. Going protean is only one way, and others will emerge.

Keeping the core company below 50 full-time employees will allow such companies to avoid the employer mandate. But it will also drive up ObamaCare’s cost, because most of the workers in the new corporate entity will be eligible for government subsidies through ObamaCare’s health insurance “exchanges.” This will drive up the cost of ObamaCare wherever those subsidies exist.

Health insurance premiums may as much as double for some small businesses and individual buyers in the U.S. when the Affordable Care Act’s major provisions start in 2014, Aetna Inc. (AET)’s chief executive officer said.

While subsidies in the law will shield some people, other consumers who make too much for assistance are in for “premium rate shock,” Mark Bertolini, who runs the third-biggest U.S. health-insurance company, told analysts yesterday at a conference in New York. The prospect has spurred discussion of having Congress delay or phase in parts of the law, he said.

“We’ve shared it all with the people in Washington and I think it’s a big concern,” the CEO said. “We’re going to see some markets go up as much as as 100 percent.”…

Premiums are likely to increase 25 percent to 50 percent on average in the small-group and individual markets, he said, citing projections by his Hartford, Connecticut-based company.

I can also tell you that, so far, I have detected no serious effort on the part of Democrats to delay anything. Frankly, I think hard core supporters of the new health law and the administration are in denial about what is coming.

I expect more health insurers to be echoing the Aetna comments in coming weeks.

Tennessee faces a decision this week about health insurance exchanges created by the Affordable Care Act.

I’m not a fan of the law. The more I know, the more harmful I think it will be for small businesses and costly for state governments and the federal government. It does nothing to address the cost of health care in our country. It only expands a broken system…

Since the presidential election, we’ve received 800-plus pages of draft rules from the federal government, some of which actually limit state decisions about running an exchange more than we expected.

The Obama administration has set an aggressive timeline to implement exchanges, while there is still a lot of uncertainty about how the process will actually work. What has concerned me more and more is that they seem to be making this up as they go.

In weighing all of the information we currently have, I informed the federal government today that Tennessee will not run a state-based exchange. If conditions warrant in the future and it makes sense at a later date for Tennessee to run the exchange, we would consider that as an option at the appropriate time.

On the same day he met with President Barack Obama (D) at the White House, New Jersey Gov. Chris Christie (R) vetoed a bill that would have implemented a key part of ObamaCare:

New Jersey Gov. Chris Christie (R) became the latest state chief executive to rebuff President Barack Obama’s health care reform law Thursday by vetoing a bill that would have created an online marketplace for uninsured residents to shop for health insurance.

At the Volokh Conspiracy, my occasional co-author Jonathan Adler dresses down PolitiFact-Georgia for declaring “false” my claim that Georgia law prohibits state employees from implementing an ObamaCare Exchange. If you place faith in “fact checkers,” you might not want to read it. My response to PolitiFact-Georgia is here.
